The hypothesis by Coleman was that the product of the ob+ gene was the appetite suppressing hormone. Hence, the homozygous ob/ob mutant are in a position to synthesize that hormone, and its circulating level would be zero. He also hypothesized that the product of the db+ gene was the receptor for the appetite-suppressing hormone. Thus, the homozygous db/db mutant would be able to synthesize the hormone but would not be in a position to respond to it. It would eat excessively and produce large amounts of body fat, which in turn would produce large amounts of appetite-suppressing hormone . In the absence of a receptor, the db/db mutant's hormone level would remain abnormally high.
Coleman's hypothesis were confirmed when the precise functions of the ob+ and db+ genes were determined. The peptide hormone encoded by the ob+ gene was named Leptin.

Answer . These two molecules form what is known as a triglyceride or a fat. Two common forms of triglycerides are saturated and un saturated fats.. so basically lipids

The urinary tract collects and stores urine and provides a passage for urine to be expelled from the body. The ureters are about 25-30 cm long and carry urine from the kidneys to the bladder.
B, I think, because by saying that the ice cube has a lower heat capacity means that it cannot stead heat enough to last longer then the water and pool.
